While you're here, how about checking out the Astronomy Book List ?

Hello,

I've recently taken photos of the Moon with my Meade LX200 SCT 8"
using the Meade apochromatic barlow (3 lenses) inside tele-converter.

And I clearly see little colored areas on the photos (red, green)
although the Moon is grey. That's not the case when I replace the
barlow with a Meade eyepiece inside the tele-converter.

A friend of mine told me he had the same problem with a Celestron
Ultima barlow. Are you aware about such barlow chromatic problem ?

Regards,
Frank Roussel
